specification.

- My invention relates to improvements in -hydrocarbon burners designed with special reference for use in connection with cooking and heating-stoves.

The primary object of the invention is to provide a generally-improved device of this class which will be exceedingly simple in construction, chea of manufacture, efficient in use, and much' etteradapted to its intended purposes than any other device of the same class with which I am acquainted.

Another object is to provide a burner of or detached from any ordinary cookingstove, the present embodiment being attached to a central bed-plate corresponding in its outline or contour to the central plate of an ordinary cooking-stove, the gas-generatin -pipe or vaporizing portion bein suspen ed within the fire-box and direct y beneath the stove-top or plates, while the oil or vapor-catchin base-pan is mounted near the bottom 0 the fire-box and is rovided with a flamereader-head disposed directly beneath the urner-tip and mixer-opening whereby to produce a maximumamount of heat, where most desired, with a minimum consum tion of fuel." By regulating the drafts, y means of the ordinary damper attachmentsof the stove, the proper-amount of air is admitted to the mixer to mingle with the vapor at the point of combustion,

thereby creating an intense clear white heat and reducing the formation of soot and dirt to a minimum.

. With these and other ends in view, the invention consists in the novel construction,

, arrangement and combination of parts, herelnafter described, illustrated in the accompanyin drawings, and particularly pointed out in t eappended claims.

Referring to the drawings, forming a part of this specification, Figure I, is a side elevation of the improved burner. Fig. II, a top plan of the same, a portion of the attached central bed or supporting-plate being brokenaway for the urpose of clearer illustration of the parts. ig. III, a central longitudinal sectional View, taken through the attached supporting-plate and oil-burnin -pan, one half of the vaporizing yoke-pipe eing removed.

Similar characters of reference designate like parts throughout all the figures of the drawings.

The improved burner, in the present instance, is mounted upon a supporting-plate 1, corresponding in its outer contour or outline to the form of the central bed-plate of an ordinary cookingrstove. The plate 1; is provided with openings through which the vertical portions of the oil-feeding inletpipe 2, and vapor outlet-pipe 3," pass, said oil inlet-pipe being secured in position by means of an elbow-pi e 4, below and a nut 5, above said plate. e plate 1, is also providedwitha mixer-opening 6, provided with a depending annular flange 7. The elbowpipe 4, of said oil inlet-pipe 2, .and the lower end of said vapor outlet-pipe 3, communicate or intersect with a horlzontally-arran ed elliptical gas-generating or vaporlzing yo epipe 8, by means of cross and T-pipe fittings 9., and 10, respectively, said yoke-pipe being, preferably, made up of two U-shaped ranches or laterally-extending wings 8, having their inner or meeting ends threaded and taking into the ends of said pipe-fittings. The u per end of the oil inlet-plpe 2, is connecte to a second or horizontal oil inletpipe 11, by means of an elbow-pipe 12, said oi inletipe 11', terminating in a needlevalve-bo y 13, provided at its upper end with a screw-ca or bonnet 14, and spindle 15. The valveody 13, is provided with a depending portion 16, threaded on its exterior for connection with an oil receiving pipe or hollow wire (not shown) communieating with any suitable and. convenient source of supply.

The upper end of the vapor outlet-pipe 3, is connected to a downwardly-curved pipe or elbow 17, by means of anelbowipe 18, said downwardly-curved pipe or el 0W 17, carrying on its lower portion adepending nozzle or burner-tip 19, superposed directly over the mixer-opening 6. A base-pan 20, is carried and su ported beneath the mixeropening 6, of t e supporting-plate 1, by means of a solid vertical supporting stem 21, said stem 21, being provided with a nut or head 22, and screw-threaded at its lower end and taking into a threaded opening in the base-pan, the upper end being threaded, in an elbow-pipe 23, secured in one of the arms of the cross-pipe-fitting 9. The pan 20, is provided with a truncated cone-shaped flame-spreader-head or block 24, secured thereto by means of a cap-screw 25, and mounted directly beneath the mixer-opening 6, and burner-tip 19, above, whereby to deflect or spread 'the' burning vapor or gas, as it impinges thereon, over and above the pan 20, and against the upwardly and outwardly-extending flange or rim 25, of the latter.

The operation of the device is as follows: First, open needle-valveallowing oil to pass through the inlet and outlet-pipes until a little oil has been allowed to escape through the depending nozzle-tip 19, through the mixer-opening 6, upon and over spreader head 24, and base-pan 20; then close valve, light oil and when generating-yoke-pipe 8, becomes hot enough, gas will. escape from nozzle 19, down through mixer-opening 6, and will ignite above the base-pan depending within the fire-box of the stove; then open valve again and regulate the flow of oil for the required amount of heat desired. By regulating draft-dampers on stove the proper amount of gas and air are mixed in passing through mixer-o ening 6. As the burning-vapor or gas stri es the-flamespreader-head or block 24, it is deflected or spread out as hereinbefore described, thus insuring a complete vaporization of the oil. Furthermore, by reasonof the construction set forth provision is made for erfect conibustion for the carbon contained in the vapor fed to the flame; and the maximum degree of the heat units is developed and,

plate provided with a downwardly-extend lng flanged mixer-opening, an inlet-pipe and an outlet-pipe intersecting said supportingplate said outlet-pipe terminating in a de' pending burner-tip immediately above said mixer opening, a horizontally arranged elliptical va orizing yoke-pipe mounted immediately beneath said supporting-plate and intersected and carried by said inlet and outletipes by means of cross and T-pipe fittings, respectively, and a flanged basepan carried beneath said mixer-opening by means of a vertical stem secured to said cross-pipe fitting.

2. In a burner, an elliptical vaporizin yoke pipe comprising two U-shape branches having their ends threaded and taking into cross and T-pipefittings, oil inlet and vapor outlet pipes communicatin with said yoke-pipe through said cross an T-pipe' fittings, respectively, and a peripherally-flanged base-pan suspended beneath said yoke-pipe by means of a vertical stem secured to said cross-pipe fitting.

3. In a burner, the combination with a supporting-plate carrying a vaporizing yokepipe made up of two branches and a mixeropening provided with a depending flange, a cross and T-pipe fitting uniting said two branches of the yoke-pipe, and an oil inlet and vapor outlet pipe secured to said cross and T- )ip'e fittings, respectively; of a peripherallyanged base-pan suspended beneath said supporting-plate and yoke-pipe by means of a vertical stein secured to said cross-pipe fitting, and a flame-spreader-head carried by said base-pan and mounted directly beneath said mixer-opening.

In testimony whereof I have affixed my signature, in presence of two witnesses.
